Is it tackey to call your hair salon and cancel an appointment because of this?

I booked an appointment for a hair dye and highlights but I need to postpone it (cancel) cause I'm having major money issues. It's not until next week so it's not like i'm canceling last minute. Should I call her and tell her the reason or just cancel it? I don't want her to think I'm rude by just canceling it out of the blue.Is it tackey to call your hair salon and cancel an appointment because of this?
Just cancel it. You don't need to say why. Just say you'll reschedule when you can.Is it tackey to call your hair salon and cancel an appointment because of this?
